The mother of Maxwell, 3, and Ace, 2, isn't shy about showing off her body. Just recently, while promoting her new workout collection, Simpson posted a picture of her muscular legs on Instagram on Nov. 30. "Lunge your bunz into @macys and get The Warm Up by @jessicasimpsonstyle #macysexclusive," she wrote along with a photo of her in a pair of short shorts.

According to a press release The Warm Up is "a true performance collection but a balance of fashion and function,” and pieces retail between $24 and $49.
